Add ViewsConfigUpdater deprecation support for update_table_css_class

This looks right. Double checked that the other two methods are actually called by ::updateAll() already just in case we'd missed something there too, but that looks fine so this is just bringing the three together now.

Trying to update all the existing config which we also missed and the new deprecation now nicely highlights

Well, it's green but had to change the actual check if we want to add the class, didn't check if this had other effects

Left 1 question the MR

Updated to 11.2
